Traction control light and ABS light

Hi all... need help diagnosing this problem... both my traction control light and ABS light come on, then three starts later, they go off, only to come on again after driving a few minutes. This has been going on a week now or more... We've been in a major deep freeze here in Calgary for a month now...and wondering if something like a wheel sensor might be freezing up?? Thanks!

Re: Traction control light and ABS light

When this happened to our '01 E46, it turned out to be the steering column angle sensor that failed, although any of the wheel sensors could have caused the same combination of dash warning lights. It took the dealer's computer to identify which one. I don't know whether your '98 even has a steering column angle sensor, but you probably need to have the dealer hook it up to find the specific failure.

interesting site... will have to check to see

which ABS module I have... meantime, my traction and abs light come on at startup... then go off... then come back on after a few seconds... abs works while the lights are off... but doesn't work when their on... very odd behaviour. I'm guessing a scan should be the next move...Dan 98 528i[IMG]

Any ideas on why my ABS,traction and service lights come on when turning the wheel and when either braking or accellerating the ABS system engages and the brakes dont work?It doesnt happen every time but has gotten more frequent and I have been driving one of my trucks because I am afraid I will get into an accident if it happens at the wrong time

Do a Goggle search on the term "BMW Trifecta". Save yourself a lot of agony by getting the car scanned. If it's the Control Module both Module Master and BBS-Reman are good choices for module rebuilding, much less expensive than buying and then coding a new module. If the scan reports wheel sensors replace with genuine OEM sensors. E39s are very sensitive to this. Generic, non VDO or Bosch sensors may or may not work, will fail early if they do work.
